Abstract
A cylinder has an insulating gas boundary layer (IGBL) across the cylinder wall inner surface, the IGBL formed by injection of an insulator fluid into the combustion chamber of the cylinder. In one implementation, a pressure differential is engineered between the top region of the cylinder and the bottom region of the cylinder. In yet another implementation, the insulator injection pressure is temporally modified in synchronicity with the piston cycle and/or in accordance with other temporal factors to provide appropriate IGBL coverage.
Claims31
An assembly comprising:
- a cylinder having an inner surface and a combustion chamber;
- a piston moveably positioned in the cylinder;
- and
- one or more insulator fluid injection ports in the inner surface of the cylinder, the ports configured to transfer an insulator fluid into the cylinder forming an insulating gas boundary layer between the inner surface of the cylinder and the combustion chamber.
1 more element
A cylinder comprising:
- a cylinder wall having an inner surface encompassing a combustion chamber;
- one or more insulator fluid injection ports along the inner surface of the cylinder wall;
- and
- one or more insulator fluid passages configured to receive insulator fluid and transfer the insulator fluid through the one or more insulator fluid ports forming an insulating gas boundary layer at an interior surface of the combustion chamber.
1 more element
A method comprising:
- providing a cylinder having an inner surface and a combustion chamber;
- and
- injecting insulator fluid in gas phase into the cylinder, the gas-phase insulator fluid forming an insulating gas boundary layer between the inner surface of the cylinder and the combustion chamber.
